Frequently Asked Questions
Everything you need to know about Common Transit, T1/T2 and NCTS
What is a T1 transit declaration?
A T1 is a customs transit declaration used for non-Union goods moving between two points within the Common Transit area without payment of import duty. The declaration is submitted through NCTS and accompanied by a printed TAD that travels with the goods.
What is the difference between T1 and T2?
T1 covers non-Union goods (e.g., goods imported into the UK from outside the EU that need to move under customs control). T2 covers Union goods that need to cross a non-Union territory while keeping their Union status — for example, EU goods moving through Switzerland or the UK to another EU member state.
Do I need a transit guarantee?
Yes. The Common Transit Convention requires every transit movement to be covered by a financial guarantee equal to the potential customs debt. This can be a comprehensive guarantee (CGU) for regular traders or an individual guarantee (cash deposit, voucher or undertaking) for one-off movements. We can arrange both.
What is NCTS Phase 5?
NCTS Phase 5 is the upgraded version of the New Computerised Transit System, fully deployed in 2024–2025. It introduces a new message set with additional data elements covering parties, itinerary, security and house consignments. All transit declarations must now be filed using the Phase 5 specification.
How long does a T1 take to issue?
Most T1 declarations are filed within 30 minutes of receiving the commercial paperwork. The TAD and MRN are then sent to the driver before the truck reaches the office of departure, so there is no waiting time.
What is a TAD and an MRN?
The TAD (Transit Accompanying Document) is the printed document that travels with the goods. The MRN (Movement Reference Number) is the unique 18-character reference assigned to the movement by NCTS. The MRN is printed on the TAD and quoted at every office of transit and destination.
Which countries are in the Common Transit area?
The Common Transit Convention covers the 27 EU member states plus the United Kingdom, Switzerland (incl. Liechtenstein), Norway, Iceland, Türkiye, North Macedonia, Serbia and Ukraine. Goods can move under a single T1/T2 transit between any of these contracting parties.
Do you handle movements to and from Turkey?
Yes. Türkiye is a contracting party to the Common Transit Convention, so T1 and T2 transits between the UK/EU and Türkiye are routine for our team. We also provide all communication in Turkish for Turkish hauliers and shippers.
What happens if a transit is not discharged?
An undischarged transit triggers an enquiry procedure (IE142) and, ultimately, a claim against the guarantee. We monitor every declaration we submit and proactively resolve issues before the discharge deadline expires.
How much does a T1 cost?
